Abstract

The 21GHz-band satellite broadcasting system is studied for transmission channels to deliver ultra high definition TV, 3D television and so on. The 21GHz-band suffers from severe fading due to rain, a fading mitigation technique forming a boosted beam with an array-fed reflector is effective for the 21GHz-band satellite system. Therefore, we designed and manufactured an experimental model of an array-fed imaging reflector antenna for the 21GHz-band broadcasting satellite system. We verified the characteristics by measurement. A 7dB boosted beam has been successfully obtained.
